A hectare is a unit of area measurement commonly used in land measurement. It is equivalent to 10,000 square meters (approximately 2.47 acres). The hectare is primarily used in the measurement of land as part of the metric system, particularly in agriculture and forestry to express the size of land plots. This unit is recognized and used worldwide, helping to provide a common reference for land area that is easily comparable across international boundaries.

What Is a Hectare?

A hectare is a metric unit of area that is widely used to measure large plots of land. It is defined as a square with each side measuring 100 meters, resulting in an area of 10,000 square meters

This unit is commonly employed in fields such as agriculture, forestry, and land planning, providing a standardized measurement for comparing land sizes internationally. Typically, a hectare is about the size of a standard sports field, making it a practical unit for visualizing substantial areas.

Tools to Measure Hectare

Tools to Measure Hectare
  1. Laser Rangefinders: These devices use a laser to determine the distance between the rangefinder and a specific target. When used in conjunction with other mapping tools, they can help precisely define the boundaries of a plot measured in hectares.
  2. LiDAR Systems: LiDAR (Light Detection and Ranging) technology can be used to measure distances using laser light. This technology is often mounted on drones or airplanes to capture detailed topographical data over large areas, which can then be used to calculate area in hectares accurately.
  3. RFID Location Tracking: For ongoing projects that require monitoring over large areas, RFID (Radio Frequency Identification) tags can be placed at various points across a hectare. The exact position of these tags can be tracked and monitored using RFID readers to map and measure the area.
  4. Infrared Aerial Photography: This method involves using infrared cameras mounted on aircraft to capture imagery that can reveal boundaries and other details not visible in standard photos. The images are then analyzed to measure the area in hectares.
  5. Robotic Total Stations: These are advanced versions of traditional total stations that can automatically track, measure, and calculate distances and angles. They are highly accurate and can operate autonomously, making them perfect for large-scale land measurement.
  6. Geographic Information System (GIS) Software: GIS is a powerful tool that integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. GIS can be used to process data from satellite imagery, GPS, LiDAR, and other sources to calculate areas in hectares.
  7. Echo Sounders: While typically used for underwater mapping, echo sounders can be adapted for floodplain mapping and large, waterlogged area calculations. They work by emitting sound waves and measuring the echo to determine distance.

How do you calculate the Hectare?

Rectangle or Square:

  • Measure the length and width of the area in meters.
  • Multiply the length by the width to get the area in square meters.
  • Divide the area in square meters by 10,000 to convert it to hectares.
Example: If a rectangular field has a length of 100 meters and a width of 50 meters, the area in square meters is 100 m × 50 m = 5,000 sq m. Dividing 5,000 sq m by 10,000 gives 0.5 hectares.


  • Measure the radius of the circle in meters.Use the formula for the area of a circle: Area = π × radius² (where π is approximately 3.14159).Divide the result by 10,000 to convert it to hectares.
Example: If a circular plot has a radius of 20 meters, the area is π × (20 m)² = 1,256.64 sq m. Dividing 1,256.64 sq m by 10,000 gives approximately 0.12566 hectares.

Irregular Shapes:

  • If possible, divide the shape into simpler shapes (like triangles or rectangles), measure these areas separately using the methods above, and sum them up.
  • Alternatively, use GPS or a digital mapping tool to measure the area directly in hectares.

Understanding how to convert hectares to other units of area is essential when dealing with various measurement systems. Whether you are managing land, planning agricultural activities, or engaged in real estate, accurate conversions between hectares and other units ensure effective communication and planning. Here’s a straightforward guide to converting hectares to and from other common units of area:

Hectares to Square Meters:

1 hectare = 10,000 square meters
  • Multiply the hectare value by 10,000 to convert to square meters.
  • Example: 3 hectares is 3 x 10,000 = 30,000 sq m.

Square Meters to Hectares:

10,000 square meters = 1 hectare
  • Divide the square meter value by 10,000 to convert to hectares.
  • Example: 20,000 sq m is 20,000 ÷ 10,000 = 2 hectares.

Hectares to Acres:

1 hectare = 2.47105 acres
  • Multiply the hectare value by 2.47105 to convert to acres.
  • Example: 5 hectares is 5 x 2.47105 = 12.35525 acres.

Acres to Hectares:

1 acre = 0.404686 hectares
  • Multiply the acre value by 0.404686 to convert to hectares.
  • Example: 10 acres is 10 x 0.404686 = 4.04686 hectares.

Hectares to Square Kilometers:

100 hectares = 1 square kilometer
  • Divide the hectare value by 100 to convert to square kilometers.
  • Example: 200 hectares is 200 ÷ 100 = 2 sq km.

Square Kilometers to Hectares:

1 square kilometer = 100 hectares
  • Multiply the square kilometer value by 100 to convert to hectares.
  • Example: 3 sq km is 3 x 100 = 300 hectares.

Hectares to Square Miles:

1 hectare = 0.00386102 square miles
  • Multiply the hectare value by 0.00386102 to convert to square miles.
  • Example: 100 hectares is 100 x 0.00386102 = 0.386102 sq mi.

Square Miles to Hectares:

1 square mile = 258.998811 hectares
  • Multiply the square mile value by 258.998811 to convert to hectares.
  • Example: 2 sq mi is 2 x 258.998811 = 517.997622 hectares.
